Abstract

An actuator comprises a housing, a motor (5), an actuating member (11, 12) and a screw mechanism (2) providing a linear movement of the actuating member (11, 12) with respect to the housing in response to a rotational movement of the motor (5), which screw mechanism (2) comprises a screw (17, 47) and a nut (13, 46) one of which is rotatably supported with respect to the housing by means of an angular contact bearing, and a reduction gear means (4). The actuating member (11, 12) and the reduction gear means (4) are situated at opposite ends of the screw mechanism (2).
